We chose to package these particular configurations based on performance and reliability. Our 411 Kits use a 2.100 rod journal as opposed to a 2.000. This provides additional material in a critical are for strength which is known as overlap between main and rod journals. The strokes used for 411, 422, and 426 allow for additional rod length to be used which reduces loading on piston and block and also increase piston dwell time for added power.
